应用最为广泛的是采用单端基准带系统的接地信号源。
The big no-no is a grounded source using a referenced single-ended system.
接地信号源的电压信号以系统地线作为参考点，比如建筑物或大地。
A grounded source is one in which the voltage signals are referenced to a system ground, such as earth or building ground.
在接地信号源RSE测量系统中引入接地环路会导致所测的信号源电压值产生误差。
The hazard of using an RSE system with a grounded signal source is the introduction of ground loops, a possible source of measurement error.
未接地信号源的信号(比如电压)没有相应的、诸如大地或建筑物这样的绝对参考点。
A floating source is a source in which the voltage signal is not referenced to any common ground, such as earth or building ground.
常用的指导方案确定测量系统选用接地信号源的微分或NRSE测量系统，以及未接地信号源的RSE测量系统。
The general guideline for deciding which measurement system to pick is to measure grounded signal sources with a differential or NRSE system, and floating sources with an RSE system.
信号源可接地或是未接地。
